ABSTRACT:
A motor vehicle having an internal combustion engine and multi-ratio transmission is launched from a neutral idle rest condition. At neutral idle, the transmission is controlled such that the input and output members are decoupled. During vehicle launch, engine output is limit controlled to achieve desired shift quality as the transmission progressively couples the input and output members to transfer torque to the vehicle drive wheels.
